Description

Technical Field

[0001] This application relates to the field of mining machinery technology, and in particular to a roller mechanism for a mining machinery conveyor. Background Technology

[0002] As is well known, mining machinery and equipment refers to machinery specifically used for mining, mineral processing, and prospecting. A large number of cranes, conveyors, ventilators, and drainage machinery used in mining operations are collectively referred to as mining machinery and equipment.

[0003] Currently, in mining operations, mineral transport is typically accomplished using conveyors. Conveyors are material handling machines that continuously transport materials along a defined route. They can transport materials horizontally, at inclines, or form spatial transport lines. The transport lines are generally fixed. To increase mineral transport capacity and protect the conveyor belt, idlers are usually installed at equal intervals at the bottom of the belt. However, the applicant has found that existing idler mechanisms, once put into use, make it difficult to adjust the height of the idlers according to requirements. Furthermore, after prolonged use, if the idlers are not subjected to balanced and stable forces, they are prone to deformation, affecting the normal operation of the idler mechanism and rendering them impractical.

[0004] Therefore, in response to the aforementioned technologies, we propose a roller mechanism for a mining machinery conveyor. Utility Model Content

[0005] The purpose of this utility model is to provide a roller mechanism for a mining machinery conveyor to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A roller mechanism for a mining machinery conveyor, comprising:

[0008] Base;

[0009] An electro-hydraulic actuator is mounted in a base via a mounting groove. The output end of the electro-hydraulic actuator is fixedly connected to a connecting seat, and two support plates are fixedly connected to the connecting seat.

[0010] The main roller shaft has connecting shafts fixedly connected to both ends. The connecting shafts are rotatably connected to the support plate through connecting holes, and the ends of the two connecting shafts that are far apart from each other are fixedly connected to the auxiliary roller shaft through a reversing coupling.

[0011] Two supports are fixedly connected to the base, and the opposite ends of the two supports are rotatably connected to the auxiliary roller shaft through a reversing coupling.

[0012] An auxiliary component, which is disposed within the base, is used to provide auxiliary support for the two auxiliary rollers;

[0013] A support assembly disposed within a base for supporting the base in its place of use.

[0014] As a further embodiment of this utility model: the auxiliary component includes two electro-hydraulic actuators, both of which are set in the base through connecting grooves. The output end of the electro-hydraulic actuator is fixedly connected to a mounting base, and the other end of the mounting base is rotatably connected to a support plate. The support plate is in close contact with the auxiliary roller shaft.

[0015] As a further embodiment of this utility model: the support assembly includes four support columns, all of which are disposed in the base through strip grooves, and the other end of each support column is fixedly connected to a support seat.

[0016] As a further improvement of this utility model, the bottom of each of the multiple support seats is fixedly connected with an anti-slip rubber pad.

[0017] As a further improvement of this utility model, the connecting shaft is rotatably connected to the connecting hole via a connecting ring.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] By setting up a support assembly, the base is supported and placed in the usage position through the cooperation of multiple support columns and support seats. Then, by activating the electro-hydraulic push cylinder, the main roller shaft is adjusted to the appropriate position through the cooperation of the connecting seat, support plate, and connecting shaft. Then, through the reversing coupling, the two auxiliary roller shafts are placed in the appropriate position. At the same time, by setting up auxiliary components, the support plate is tightly fitted with the auxiliary roller shaft through the cooperation of the electro-hydraulic push rod and the mounting seat, thereby achieving the purpose of auxiliary support for the auxiliary roller shaft. Its overall structure is relatively simple, which facilitates the corresponding adjustment of the main roller shaft and auxiliary roller shaft, improves its applicability, and compared with the existing technology, it is easier to provide auxiliary support for the auxiliary roller shaft, avoids deformation due to long-term use, ensures normal use, and has good practicality.

[0028] Base 1;

[0029] Electro-hydraulic push cylinder 2 is installed in base 1 through mounting groove. The output end of electro-hydraulic push cylinder 2 is fixedly connected to connecting seat 3. Two support plates 4 are fixedly connected to connecting seat 3.

[0031] Two supports 9 are fixedly connected to the base 1, and the opposite ends of the two supports 9 are rotatably connected to the auxiliary roller shaft 8 through the reversing coupling 7.

[0032] An auxiliary component is located inside the base 1 and is used to provide auxiliary support for the two auxiliary rollers 8.

[0033] A support assembly is disposed within the base 1 and is used to support the base 1 in the position of use.

[0034] The idler roller mechanism of this mining machinery conveyor can be used by setting up a support component. Under the action of the support component, the base 1 is supported and placed in the use position. Then, by activating the electro-hydraulic push cylinder 2, the main roller 5 is adjusted to the appropriate position through the cooperation of the connecting seat 3, the support plate 4, and the connecting shaft 6. Then, the two auxiliary rollers 8 are placed in the appropriate position through the set reversing coupling 7. At the same time, the auxiliary component can be set up to provide auxiliary support for the auxiliary rollers 8, so as to prevent deformation after long-term use.

The output end of the electro-hydraulic actuator 10 is fixedly connected to the mounting base 11. The other end of the mounting base 11 is rotatably connected to the support plate 12. The support plate 12 is tightly fitted with the auxiliary roller shaft 8.

With the cooperation of the electro-hydraulic actuator 10, the mounting base 11, and the support plate 12, the support plate 12 is tightly fitted with the auxiliary roller shaft 8, thereby achieving the purpose of auxiliary support for the auxiliary roller shaft 8.

[0037] exist Figure 1-4 The support assembly includes four support columns 13, which are all set in the base 1 through strip grooves. The other end of each support column 13 is fixedly connected to a support seat 14. The bottom of each support seat 14 is fixedly connected to an anti-slip rubber pad 15 to increase the contact friction of the bottom. The connecting shaft 6 is rotatably connected to the connecting hole through a connecting ring 16. The connecting ring 16 is designed to reduce the rotational friction between the connecting shaft 6 and the connecting hole.

The installation position of the control switches is selected according to actual usage needs to facilitate operation and control by the operator. The technology is already very mature and can be implemented.

At the same time, the two auxiliary roller shafts 8 are placed in the appropriate position by setting the reversing coupling 7.
